I have received an intermediate winding bridge from Chile and I was told that the pillars from the KW movement could be used - beep...
Also, it should be threaded - beep...

I can turn the pillars to the correct length/depth and I can cut threads, but it seems wrong as the customer paid for the completed part and not a DIY bridge.

We already agreed on a price for the conversion and I am not going to charge a higher price for this extra work.

Uneven QC in my opinion.
Sure, theres was two differtent batches of KW, as i posted before even with videos. Theres older ones like gen specs when you need to turn the pillars to allow extra 1mm material of new bridge (old one was 1mm and new one with hole was 2mm). New batches comes with already recess of 1 mm on the pillar so no need to turn the pillars 1mm extra.

What threading you made? the ones for the báscule and the spring? for sure some customers ask me not to do the threading as they will use generic screws, so for sure you cant tell if was a QC issue or just a custom made bridge.
I think now even with chinese Tap and die can make with no problem threading on brass.

Regards.

Both intermediate winding bridges were ordered at the same time, so they should be identical.

The holes for the yoke and yoke spring were not threaded.

Still, Jorge, it is no problem and I have sorted it without any issues.

I really miss wearing my WL SF240, but I had to let the movement go when funds were low, now to build the one and only.

Just working on building my own welded lug from scratch, soldering of the lugs included.

That's why I'm looking for a river midcase.

Is that the one I sent to you back in the day? Do you have any pictures?
